Macs can access Windows remote desktop connections (RDP or Remote Desktop Protocol). The app you can download is called the "Windows App".
It looks like this in the Apple Store:
To use the app, in the upper right is a + sign with the options.
You can add a work or school account, if your account is assigned a connection. If you know the remote hostname, you can use the Add PC option. If you have a workspace, you can use that option and add the workspace connection information with that option.
